Allergy, 55 Suppl 64, 17-27 (2001-04-09)
The primary mechanism of antihistamine action in the treatment of allergic diseases is believed to be competitive antagonism of histamine binding to cellular receptors (specifically, the H1-receptors), which are present on nerve endings, smooth muscles, and glandular cells. This notion

Non-sedating H1-antihistamines are the recommended first-line treatment for chronic spontaneous urticaria. While efficacy studies usually apply continuous daily treatment regimens, many patients take their medication on demand. In this randomized, double-blind trial we tested whether on-demand H1-antihistamine desloratadine in standard

The efficacy of amantadine in alleviating motor symptoms of Parkinson's disease may be mediated in part by stimulation of cerebral dopa decarboxylase (DDC) activity, secondary to antagonism of N-methyl-D-aspartate (NMDA) type glutamate receptors. We tested the specific hypothesis that amantadine

The extent of the distribution of H(1)- antihistamines into the skin and H(1)-antihistamine activity in the skin are clinically relevant in the treatment of allergic skin disorders. In a prospective, randomized, double-blind, parallel-group, multiple-dose study, we gave fexofenadine 180 mg

Cold urticaria is a rare but severe and potentially lethal condition. It is primarily treated symptomatically with H(1) -antihistamines. However, patients have a variable response to these drugs and, to date, it has not been possible to predict readily the
